Abstract: 805,484. Preventing incrustation. VERMEIREN, T. I. S. April 13, 1956 [April 29, 1955], No. 11321/56. Class 123(1) .To prevent incrustation of surfaces by liquids giving rise to the formation of calcareous, siliceous or magnesia deposits, the liquid is passed through a restricted passage adjacent a magnet pole so that it is subjected to a magnetic field of great intensity. The liquid may be passed between pointed or rounded pole pieces providing the restricted path (Figs. 1-4, not shown). In the construction shown in Fig. 5, a magnet 5 is disposed in a container 4 so that its opposite ends 1, 2 respectively restrict the inlet and outlet passages to annular gaps 3 across which a strong field exists. In another form, Figs. 7, 8, four magnets 5A are mounted within a casing 4 with narrow gaps between their adjacent ends 1, 2 which are of opposite polarities. The liquid is constrained to enter the space enclosed by the magnets and pass outwardly through the gaps by baffle plates 6, 7.

Magnetos, driving.-A resilient drive for transmitting rotation from an internal-combustion engine to a magneto &c. comprises two shafts and a cylinder of springy metal all coaxially arranged, the cylinder being slit from end to end and secured for rotation on one side of the slit to one of the said shafts and on the other side of the slit to the other shaft, and means for damping oscillations set up in the cylindrical spring. In the construction shown in Figs. 1 and 4, the coupling comprises two shafts b, c arranged one inside the other and terminating in radial flanges b<2>, c<2> which are bent back again to form overlapping cylindrical drums b<3>, c<3>. The drum b<3> of one shaft is cut as shown at b<5>, b<6>, Fig. 4, so that it forms a C spring integral at its end b<6> with the shaft. Its other and free end is secured by a bolt d<1> to the drum c<3> of the shaft c and to a spider d which is connected by bolts d<3> to the flange c<2> of the shaft c, the bolts working in: elongated slots in the flange b<2> of the shaft b, so as to allow limited relative motion between the shafts. A ring e of friction material is placed between the flanges b<2>, c<2>, and these are pressed together by a spiral spring c<9> to damp oscillations in the cylindrical spring b<3>. The coupling is arranged inside, a hollow shaft a<1> rotatable in the time gear casing a, and provided with a skew wheel a<3> by which it is driven from the engine. The shaft a' rotates the shaft b through interengaging serrations a<4>, b<4>, the rotation is transmitted to the shaft c through the cylindrical spring b<3>, and thence to a toothed wheel f<1> on the magneto shaft f through serrations c<4> on the drum c<3>. The numbers of the serrations c<4> and a<4>differ by one, or they have no common factor, to enable fine timing adjustments to be made. In the construction shown in Figs. 6 and 7, the cylindrical spring is formed separate from both shafts. A diametrical cut i<3> is made through a disc i and its cylindrical flange i', and the flange is partly separated from the disc by a cut i<2>, leaving each end of the cylindrical spring so formed integrally secured to a half of the disc. One half of the disc i is then secured by bolts i<6> to one shaft of the coupling, and the other half by bolts i' to the second shaft.

Title: Improvements relating to electrical reverberation circuits
Inventor: VANDERLYN PHILIP BARNET
IPC: G10K15/12
Filed: 1962-03-28
Abstract: 1,040,574. Reverberation systems; stereophonic systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 27, 1963 [March 28, 1962], No. 11796/62. Heading H4R. An electrical reverberation circuit includes a direct signal path and a plurality of individual reverberation circuits each of which produces a delayed component and an undelayed component, the circuits being connected to form a reverberation signal path, and means for combining a direct signal from the direct signal path with a reverberation signal from the reverberation signal path in desired proportions, means being provided for substantially cancelling the undelayed components from the reverberation signal path. Signals from input terminal 1 (Fig. 1) are applied to adjustable attenuators A 1 , A 2 , and to reverberators R 1  ... R N  providing delayed and undelayed output signals. A differencing network 3, conveniently a pair of inductive ratio arms, is such that when attenuator A1 is suitably adjusted the undelayed signals applied to it from both paths cancel while the delayed signals pass to a variable attenuator A3. The outputs of attenuators A2, A3 are added in combining network 4 to provide a direct signal with an added artificial reverberation signal at output terminal 2. Attenuators A 2 , A 3  and network 4 may be omitted, an output being taken from network 3 directly. Attenuator A 1  is then varied to vary the proportions of the direct and reverberated signals. In this arrangement attenuator A 1  is preferably divided into two attenuators, one of which is adjustable to cancel out the signal from chain R 1  ... R N  while the other controls the magnitude of the direct output signal. A two-channel stereophonic system may have a circuit arrangement as shown in Fig. 1 in each channel. Preferably, however, a single chain of reverberators R 21  ... R 2N  (Fig. 2, not shown) is used for both channels. Stereophonically related input signals traverse separate direct signal paths each including a variable attenuator. Combined stereophonically related input signals are applied to reverberators R 21  ... R 2N  and to a variable attenuator A 21  in parallel with the reverberators. The output signals from the reverberator chain and attenuator A 21  are applied to a differencing network 6. Only the reverberation signal appears at the output of network 6 and this is applied through a variable attenuator A 22  to reverberators R 2L  and R 2R  which have equal delays but feedback of opposite sign to provide quasi-stereophonic quality to the reverberated signals. The output of reverberator R 2L  is added to the L channel and the output of reverberator R 2L  is added to the R channel. In a further stereophonic arrangement (Fig. 3) two subtracting networks 10, 11 are provided, together with individual attenuators A 31 , A 35  for one channel and individual attenuators A 32 , A 36  for the other channel. Reference has been directed by the Comptroller to Specification 1,001,518.
